加密
通过密码学控制保护数据的机密性和完整性。
加密由以下 NIST CSF 2.0 成果定义：PR.DS-01 (The confidentiality, integrity, and availability of data-at-rest are protected); PR.DS-02 (The confidentiality, integrity, and availability of data-in-transit are protected)。 对照映射 通过 ISO 27001, CIS v8.1, PCI DSS, CMMC, 800-53, HIPAA 和 NIS2 中已发布的对照表完成映射。 编辑说明 在 SOC 2, GDPR 和 DORA 中经编辑映射。 本站数据中无映射 本站数据中 Essential Eight, CPS 234 和 Cyber Essentials 无映射。

关于加密
加密通过使数据在没有正确密钥时无法被读取，从而保护数据的机密性和完整性。各框架要求敏感数据在静态和传输过程中均须使用强且当前有效的密码学进行加密，但很少指明具体算法：PCI DSS 要求采用由行业标准定义的“强密码学”，美国联邦系统必须使用经 FIPS 验证的模块，ASD 的 ISM 则列出了经批准的算法和协议。密钥管理与算法同样重要：须依据成文程序生成、分发、存储、轮换和退役密钥，PCI DSS 在 3.6 和 3.7 中对此有明确规定。
